Abstract

Write requests are performed against one or more resources of a resource group in a persistent and atomic manner. When a write request is received, a backup resource group is updated to reflect data in a current resource group. Thereafter, the write request is performed against the backup resource group. After successfully performing the write operation(s), the backup resource group and the current resource group are swapped in an atomic, consistent manner, such that the backup resource group is now the new current resource group.
